Etymology - combination of jibberish and literature.
Words used by spam technology to create the appearance of being a real email, but in fact, being utter nonsense when read as a whole.
My co-worker Mike coined this term today in the middle of conversation.
Me: Wow! Jibberlit. That's brilliant. Did you just make that up?
Mike: Yeah. Yeah. I think I did.
Me: It's awesome. It's perfect. Everyone should know that.
Mike: You can blog it.
Ha. Well, I don't know about everyone now knowing the term jibberlit, but definitley three people now know the term. Go forth people and spread the good word! :)
